VPO4
VPO4 is a stable, semiconducting transition-metal phosphate used as a model material in solid-state research.
About VPO4
VPO4 is a transition-metal phosphate that exists as a thermodynamically stable phase on the convex hull. As a semiconducting material, it represents a significant subject of study within inorganic chemistry, characterized by a robust structural framework that supports diverse atomic configurations.
Its importance lies in its chemical flexibility and the stability of its lattice, which makes it a compelling candidate for electrochemical applications. With numerous reported structures across databases, it serves as a foundational material for understanding redox-active phosphate frameworks in solid-state science.
Key Properties
Cross-validated computational properties for VPO4, aggregated across 4 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

How It Compares
Within the transition-metal phosphates class.
Within the broad class of transition-metal phosphates, VPO4 occupies a distinct position compared to well-known battery cathode materials like LiFePO4 or LiMnPO4. While its siblings are frequently utilized for their specific lithium-ion intercalation properties, VPO4 serves as a critical structural analog that helps researchers map the stability and electronic evolution of vanadium-based phosphate systems against iron or cobalt counterparts.
